SlG'NAL-BOX.

SPECIFICAIION forming part of Letters Patent No. 447,062, dated February 24, 1891. Application filed September 11, 1889. Renewed December 5, 1890. Serial No. 373,642. (No model.)

To alii 1071,0722 it may concern Be itkno'wn that I, Bnnmon J. N OYES, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Signal-Boxes, of which the following description,

- inf'conneotion with the accompanying dnawings, is a specification, like letters and figu res on thedrawings representing like parts,

Signal-boxes for police and fire-alarm telegraph purposes have heretofore'been provided with suitable means by which a key may be employed to turn in a signal, said key be in; locked when once used for this purpose and retained until released by a proper person, the object being to preverriftnrning in alarms by malicious persons.

'lhisinv'e'ntion has for its object to provide asignal-box with suitable means whereby an alarin'maybeturned in bya key and a num her orcharacter, code or otherwise, indicating the particular key used for the purpose, impressed, embossed, or printed upon a piece ot paper or any equivalent or suitable material provided forihe purpose, so that after the alarm has been turned in the key may vbe withdrawn, -yet a correct indication or character retained.

The invention consists in the combination, with a signahtransmittcr and a key for operating ii. adapted to be inserted and withdrawn from the box containing the transmitter, of a piece of material arranged to be marked upon, embossed, or impressed by the key.

As apreferable wayot' carrying out the invention, the bit. of the key has formed on it projections variously arranged to indicate code signals or numbers, and a strip of paper is arranged in the box, which is impressed or size and shapcsuch, for instance, shown in my application, Serial No. 245,499, filed July 28, 1887. shown and havinr a suitable actuating or starting lover or arm will be employed,the said starting lever or arm beina' operativcly connected with the bar I), which is loosely the frame'c'. The frame 0 has a pin 0 which passes through a cnry'ethslotc formed in the frame 0. To turn in an alarm, a keysuch, for inlhc signalrtransmittcr.not

connected to the arm (r, having its bearing in stance, as shown at (Z, Fig. 2 is inserted in 65.

resume its normal position, a spring conscribed is not of my invention, and no claim is herein laid specifically thereto.

A strip of paper a, wound on the reel e, journaled in the frame-work, passes between suitable guide-rolls, as a and over a'roll e on to a reel c. The keys are formed,-as here- -in shown, with projections, as 2, on the bit,

either on the side or edge thereof, and the surface of the roll e substantially meets the path of movement of the edge of the bit as the key is turned, so that the projection 2 thereof will impress, print, or emboss the paper e. Each key will have the projections differently arranged, so that a codeindication is left on the paper, representing the particular key used in turning in the alarm.

To move the paper forward so as to presenta blank space for the next alarm turned in by means of a key inserted in the key; hole 1], I have provided the reel 6 with'a ratchet-toothed wheel f, and have provided a i'sliding rod f with a spring-controlled pawl 1 'which engages the said ratchet-toothed wheel f and arod'or bar f loosely connected 5 with the-sliding rodf,one end of which rod or barf enters the path of movement of the bit of the key, so that as the key is rotated in one'directiou the arm f is moved, or it may be a projection on the end of the arm 1 only to w'hielris' moved, while on returning the key to its normal position the arm f is moved in theopposite direction, moving the sliding rod f in the direction of the arrow, and thereby moving the ratchet-toothed wheelfdnc step :5 in advance.

\Vhcn a key having the indicating projections on the side of the-bit instead 9f on the edge is employed, the roll a will be located nearer the axis of the key, so that the pro jeetions willstrike on it.

In lieu of the particular construction of feeding device 'for the paper herein shown, any other feeding device operated by movement of the. key when employed in turning 22: in the alarm may he used, and any such form Idcem comes withinthe scope of this invention; nor do I desire to limit the invention to the employment of the paperin'strip form and wound on reels, as shown, as various other forms may be devised to accomplish j the same end.

, I claim-- 1.' In a signal-box containing asigna-l-trans mitter adapted to be operated by a key insorted through a key-hole, the combination,

with the key formed to print, 'impress,'oremboss a character indicating a number or equivalent by whiclr'the key is known, of a piece of material upon which the said eharacter is printed or embossed, substantially as 0 described r 2. Inasignal-box containing asignal-trans mitter, the combination, with a key adapted to turn in an alarm and formed to indicate a number or character by which it is known, of a movable piece of material upon which the said number or character is indicated, leaving a permanent record. substantially as described.

Inasig'nal-box containing-asignal-trans- 5o mitter, the combination, with a key adapted to turn in an alarnraud having projections formed on it indicating its number or equiva lent by which it is known, of a piece of material marked, impressed-or embossed by said project-ions, substantially as described.

4. In a signal-box containing a signal-transmitter, the eombinat ion, with the key adapted to turn in an alarm and tormedto mark,impress, or cmboss a piece of material to indi- 6t, cate its number or equivalent by which it is known, of a feeding device for the said ma terial, substantially as described. i

5. In a signal-box containing-asignal-transmitter, a key adapted to turn in an alarm, the bit of which has formed on it several projections, a strip of paper or equivalent adapted to be marked, impressed, or embossed by said projections, and a fecdingdevice for the said paper,substantially as and for the purposes set forth. f

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. BERNIUE J. NOYES.
